Question 1

Some professional cameras use multiple chips, one chip each for Red, Green and Blue.

Accepted Answer

Some professional cameras use a color filter array (CFA) consisting of multiple chips, with each chip dedicated to capturing Red, Green, or Blue light. These images are then merged together to create a final image with full color information.

Question 2

Typically, the smaller the size of a chip in a camera, the better the image quality.

Accepted Answer

Generally, larger chips in cameras are associated with better image quality because they can capture more light and produce less noise compared to smaller chips.

Question 3

The image that is focused on the face of the camera tube is inverted upside down from the way it appears in real life.

Accepted Answer

This is because the camera tube uses a converging lens to focus the image, which results in an upside-down image being projected onto the tube.

Question 4

In a pickup tube, if there is no light on the imaging area, the imaging area resists the flow of electricity coming from the beam.

Accepted Answer

In a pickup tube, the imaging area is coated with a photosensitive material that converts light into electrical signals. If there is no light, the photosensitive material resists the flow of electricity from the beam.

Question 5

Over the years, the pickup tubes and scanning yokes needed to drive the tube cameras have been eliminated and replaced by light sensitive chips.

Accepted Answer

This statement is true because tube cameras have been replaced by electronic cameras that use light sensitive chips instead of pickup tubes and scanning yokes.

Question 6

The face of the pickup tube is known as the .&#10;A) beam&#10;B) target&#10;C) beam aperture&#10;D) horizontal deflection coil

Accepted Answer

The face of the pickup tube is known as the target. This is because it is the surface upon which the electron beam is directed and where the image is formed in devices such as cameras and oscilloscopes.

Question 7

A CCD is made up of a site that is covered with thousands or even millions of&#10;A) transistors&#10;B) capacitors&#10;C) megapixels&#10;D) sensors

Accepted Answer

A CCD (Charge-Coupled Device) is made up of a site covered with thousands or millions of capacitors. These capacitors collect and transfer charge, making them essential for capturing images in cameras, telescopes, and other imaging devices.

Question 8

The process of a beam of electrons sweeping back and forth across the&#10;A) beaming&#10;B) inverting&#10;C) scanning&#10;D) diplexing

Accepted Answer

The process described is that of scanning, as a beam of electrons is sweeping back and forth across a surface.

Question 9

In the case of cameras that use multiple chips, light entering the camera goes&#10;A) beam splitter&#10;B) 2x extender&#10;C) lens stretcher&#10;D) none of the above

Accepted Answer

In cameras that use multiple chips, light entering the camera goes through a beam splitter. This beam splitter separates the incoming light into different paths that lead to each chip responsible for capturing a specific color (usually red, green, and blue). This allows for improved color accuracy and overall image quality.

Question 10

Each frame in the traditional NTSC system of television, previously used in&#10;A) 525&#10;B) 625&#10;C) 720&#10;D) 1080

Accepted Answer

The traditional NTSC system of television used 525 lines per frame.
